Discovery and remediation are hard, but absorbing security updates is the final hurdle. What I’m seeing in 30 Red Hat Enterprise Linux customer meetings.

Defending Your Agents Against Adversarial Trajectory Guidance (And Other Gnarly Things)
If you’ve been following Trentina, you know I’ve been beating the drum on prompt injection defense for a while now. I built a three-layer quarantine system, wrote about prompt injection in terms of epidemiology, and generally been that guy at the party who won’t shut up about how your AI agent is going to get
My Personal Mythos Moment
How I got hacked twice in one month by two different attackers — and fixed it with 3-5 AI prompts while on work calls. My personal Mythos moment.
The Prompt Injection That Copies Itself
A prompt injection doesn’t have to act to be dangerous. It can hide, copy itself, and spread agent to agent. Why AI security is an epidemiology problem, and how to respond.
MCP-Airlock Is Now Trentina: The 1377 Quarantine That Inspired Our Rename
MCP-Airlock is becoming Trentina — named after the 1377 quarantine system from Ragusa that inspired its architecture. Same three-layer defense, same gateway, better name.

Project Bluefin is Helping Prove That Dark Factories Work for Operating Systems
Six years ago, I wrote about the good, better, best approach to Linux quality when evaluating container images. The same framework applies to desktop Linux distributions – maybe even more so, because desktops have a GUI that’s notoriously hard to test automatically. Here’s what I wrote: Good: Use a bug tracker and collect problems as

Put The Tron Ares Album On and Build Something at Midnight
I’ve loved Tron since I was a kid. When I was about seven or eight years old (early 1980s!!!), my Mom took me to see Walt Disney’s Magic Kingdom on Ice at the Richfield Coliseum, which was this massive arena between Cleveland and Akron (sadly, torn down in 1999). The show had a Tron segment,

image mode Gave Me the Confidence to Go Fully Agentic
I’ve been running Claude Code on my RHEL 10 workstation for a few months now, and I have to admit, with some embarrassment, I often run it with the ominous –dangerously-skip-permissions option. It reads and writes files, executes shell commands, installs packages, modifies system configs, all without asking permission first. I’ve been letting an AI

MCP-Airlock: An Open Source Defense Against Prompt Injection in AI Agents
Update (June 2026): MCP-Airlock has been renamed to Trentina. The project has grown from a web content sanitizer into a full MCP gateway with per-consumer profiles, tool allowlists, and parameter-level access controls. The new name reflects that expanded scope — and avoids a naming collision with another MCP gateway project. The architecture described in this

My Print Screen Key Stopped Working….
My print screen key on my external keyboard stopped working. Not the one built into the laptop, that was working fine. The one on my external keyboard. It had worked fine, and then it randomly stopped working! Why? I have no idea. This kind of thing isn’t supposed to happen in computers, but we all
